FOLDING MACHINERY FOR PRINTING PRESSES.

SPECIFICATION forming part of Letters Patent No. 389,656, dated September 18, 1888. I

Application filed November 14, 1887. Serial No. 255,046. (No model.)

To all whom it may concern.-

Be it known that'I, GEORGE W. KENDALL, of St. Albans, in the county of Franklin and State of Vermont, have invented an Improvement in Folding Machinery for Printing- Presses, of which the following is a specifica tion.

' Folding-machines have been made as part of the printing-press, or else adapted to receive the sheets therefrom; but such machines can seldom be used in connection with the hand or small power presses made use of for countrynewspapers and job-work.

My present invention relates to a'cheap and easily-constructed folding apparatus that can be applied to' hand or small power printing. presses, and the movements given to the successive folding-blades are derived from a reciprocating bar, so that the only connection necessary for actuating the folder is a connection to the reciprocating bed of the press, or a crank and connecting rod, and a drivingpulley for actuating thebelts or tapes of the respective rollers. r

In the drawings, Figure 1 is an elevation of the folding apparatus with the frame in section. Fig. 2 is a similar view at right angles to Fig. 1. Fig. 3 is aplan of the folding mechanism; and Fig. 4 is a sectional plan at about the line m, Fig. 1. Fig. 5 is'a view of the sheet-supporter detached.

The side frames, A A, are connected by the cross-frames A. The frames A A have suitable legs for supporting the apparatus at the proper height. 'There are three sets of conveying-belts and the rollers for the same, and I remark that there may be any desired number of belts or tapes in each set. I have shown on the drawings only a few of the belts to avoid confusion.

The sheet, asit is delivered from the printing-press, passes in between the belts 2 and 3. These pass around the respective pairs of rollers 4 4 and 5 5, and the sheet of paper is arrested by the fence or gage 6, and it is folded downwardly between-the rollers 7 and 8 and belts!) and by the blade (3. These belts 9 and 10 pass around i the lower rollers, 11 and 12, respectively, and the folded sheet is in' a belts 16and 17 there being rollers 18 and 19,

around which the respective belts 16 and 17 pass. There is a third folder, E, that is horizontal, and receives a movement to fold and convey the sheet in between the rollers 20 and 21 and belts 22 and 23, and thereby fold the sheet the third time, and these belts 22 23 pass 1 around the respective rollers'24 and 25. The

gate or stop 26 arrests the movement of the folded sheet as it lies between the belts 22 23, and the blade F, moving vertically, carries the sheet down between the rollers 30 31 and gives to the same the fourth fold, and the sheet drops into a receptacle.

The respective sets of belts and rollers may be driven in any convenient manner; but I prefer a drum, G, driven by a belt to the pulley G, and from this drum the belt 35 passes over and gives motion to the rollers 4 and 5 and their sets of belts 2 3, and the belts 36 pass over and give motion to the rollers 7 and 8 and their respective belts 9 and 10, and the belts 37 drive the rollers 24 25 and their respective belts 22 23, and there is a belt, 40, to the vertical pulley 41, and from that the belts 42 pass to the respective rollers 18 and 19, to drive the same, and the belts 16 and 17, and the rollers 30 and 31 are driven by belts 43 from the main drum G. I, however, do not limit myself to this specific arrangement of belts for driving the respective pulleys and ranges of tapes.

The slide H is reciprocated the proper distance by an attachment to the type-bed in a frame, pivoted at 50 upon the frame A, and

at the apex of the frame 0 is a connecting-rod,

O", to the crank-arm C upon the shaft C,and

there is a vertical arm, 0 upon this crank- 5 shaft, against which the latch O on the slide H acts to move the parts when the slide H is traveling in the direction of the arrow, Fig. 4,

and when the slide H is returning in the 0pposite direction the latch C swings upon its to pivot, so as to pass by the arm 0 without moving the same, and there is a spring, 0 which acts to lift the arm 0 connecting-rod 0 frames 0, and folding-blade C after the latch O has passed beyond the arm 0 The folding-blade D is sustained in a vertical position by suitable slides at top and back portions, and it is hung by the link 60, and it crosses above the slide H, and there is a stud, 61, upon the under side in line with the inclined spring-latch 62, on the top surface of the slide H, so that as the said slide is moved endwise the incline of the latch 62 moves the folding-blade D toward the rollers 14 15 to fold the sheet between them, and the spring 63 draws back the folding-blade as soon as the latch 62 passes. On the return movement the spring-latch 62 yields as it passes the stud 61 without moving the folder D.

The rock-shalt E has an arm, E, that acts against the horizontal folding-blade E to move the same, and this rock-shaft E is swung at the proper time by the pin 65 on the slide H, coming in contact with the arm 66 on the rockshaft. The spring E draws back the foldingblade E as the slide H moves in the other direction,

The parts are so constructed and timed that upon the slide H commencing to move in the direction of the arrow the folding-blade C is 0 first brought down, then the blade D is brought up to give the second fold, and then the blade E gives the third fold as the slide H finishes its movement. Upon the return movement of the slide H the fourth folding-blade, F, is actu- 5 ated by the rock-shaft F, arm F, and slideframe F of the folding-blade F and the arm F* on the rock-shaft and the tail end 70 of the latch 0 on the slide H. On the forward movement of the slide H this tail 70 swings back and does not move the arm F. The folder F is lifted by the spring F The trough L, into which the folded sheets fall, has within it a follower, N, that is reciprocated by a bar, L, that extends to near the 5 slide H, and it is provided with a radius-bar, L, pivoted at 72, and having an inclined end, 73, against which the end of the slide H acts, and the parts are movedin the other direction by a spring, 74. This follower is moved to press the mass of folded sheets along in the trough L as the slide H completes its forward movement, and the follower draws away from such pile of sheets as the slide H commences to move back; hence there is room between the 6 5 end of the follower and the sheets in the trough for another sheet to pass down by the action of the foldingblade F, as before described.

The sheet-supporter O is in the form of a three-sided bow or loop, and it is pivoted at the rear ends to the rocking-levers O, and these have their pivots 0" upon the sides of the trough L, and the lower ends of the levers O are jointed to the projecting arm 0" on the follower N, and there is a notched lifter, P, jointed at the upper end to the sheet-supporter and acting against the end of the pivot O and pin P.

As the follower N is moved toward the pile of sheets the notched portion of the lifter rests upon a projecting end of the pivot 0 and the movement of the lever 0 causes the lifter P to raise the sheet-supporter from between the pile of sheets and the folded sheet that is being carried forward by follower N. By the time the sheet-supporter is clear of the pile of sheets the follower N has moved the last sheet against the pile of sheets, and just before the follower completes its forward movement the tail of the lifter P comes in contact with the pin 84, disconnecting the shoulder on the lifter from the pivot O, and the sheet-supporter drops down behind the pile of sheets into the position shown by dotted lines in Fig. 5. As the follower N is drawn back the lever O is swung upon its pivot O, and the supporter O is moved forward against the pile of sheets and sustains them as the follower is drawn farther back to position shown in Fig. 1.

By this construction of folding-machine I am able to deliver the folded sheets with reliability, and the successive .operations are performed in the proper times by a reciprocating movement.

I claim as my invention- 1. The combination, with the folding-blades G D E and the pairs of folding-rollers and sets of tapes, of the reciprocating bar H and the respective devices for giving motion to the folding-blades in succession by the movement of the reciprocating bar H, substantiallyas set forth.

2. The combination, with the folding-blades G and the rollers and tapes, of the frame 0, carrying such blade, the connecting-rod C rock-shaft 0*, arms 0 and O, and thelatch C, and slide H, carrying the same and giving motion to the parts, substantially as set forth.

3. The combination, with the folding-blade D and the slides and link for supporting the same, of the reciprocating slide H and the inclined spring-latch 62 upon the same for actuating the folding-blade, and the rollers and sets of tapes for conveying away the sheets, substantially as set forth.

4. The combination, with the folding-blade F and rollers 30 31, of the slide H, the rockshaft F, arms F F, and latch C on the slide for giving motion to the blade F upon the re turn movement of the slide H, substantially as set forth.

5. The combination, with the trough L, for receiving the folded sheets, the follower N, and means, substantially as specified, for reciprocating said follower, of the lever O, the link 0 connecting the follower to said lever O, the sheet-supporter O, pivotedto the lever 0, the lifter P,'connected t0 the sheetsnpporter- O, and pins for the lifter to take against, substantially as and for the purposes specified. 7 r0 Signed by me this 8th day of November, A. D. 1887.
